I use both skype and google voice (via gmail) for VOIP calls. In both cases, regardless of the client settings (there aren't many for google voice), the system audio input will increase on it's own over the course of a call.
I've had this issue for years and i've never seen an actual resolution. Stumpped.

Plist files in OSX can be of 3 different formats:
- Binary (just like the one used by com.google.GoogleTalkPluginD.plist
- XML
- JSON
Don't bother editing the binary file (by performing guesstimates, editing with an hexa editor etc); it won't work.
Instead, perform the following:
1 - Make a copy of the file to your desktop: cp ~/Library/Preferences/com.google.GoogleTalkPluginD.plist ~/Desktop/
2 - Convert the Binary Plist to an XML Plist: plutil -convert ~/Desktop/xml1 com.google.GoogleTalkPluginD.plist
3 - Edit the file with an editor (Aquamacs, TextEdit) and set the Audio Flags value to 1
4 - Convert the file back to Binary: plutil -convert binary1 ~/Desktop/com.google.GoogleTalkPluginD.plist
5 - Copy the file back to the Preferences directory: cp ~/Desktop/com.google.GoogleTalkPluginD.plist ~/Library/Preferences/
6 - REBOOT (closing and reopening the browser won't work as the plugin runs on the background. We "could" kill the process to have it restarted, but we'll leave it simple and reboot the machine).
That's all it takes. Now feel free to set your mic volume to the value you desire and it will STAY at that level while using Google Talk (it won't auto adjust based on background noise).
Audio input gain increases automatically
